This year's E3 is going to be full of exciting announcements. We're only a few months away from the release of two new game consoles: the Sony PlayStation 4 and the Microsoft Xbox One. There also promises to be huge innovations in games, gaming technology and accessories on display at this year's E3.

What can you expect to see announced this year? We've curated the highlights below, but be sure to stay tuned to Mashable all week long for breaking news, play-by-play of the bigger press conferences and hands-on with some exciting games.

What are you most excited about for this year's E3? Share your thoughts in the comments below.

Microsoft

Microsoft will kick off the festivities Monday with its press conference, starting at 9:30 a.m. PT/12:30 p.m. ET. While Microsoft revealed many of the details about the Xbox One during its May 21 announcement, we're likely to get more details about the new console.

The Microsoft press conference, which lasts an hour and a half, will probably focus on games. While we saw a few hints in May, Microsoft promised 15 titles would be released during Xbox One's first year on the market, and those would be console exclusives. Eight of those would be brand new intellectual properties. For example, we learned this week about a game based on Disney's Fantasia in development. By Dance Central creators Harmonix, it uses the Kinect sensor to let players control the music. It will be an Xbox 360 and Xbox One exclusive.

We also know some unannounced titles are going to be playable at E3, so games stand to see a lot of focus during Microsoft's press conference. There are also plenty of chances for celebrity appearances; Microsoft has a precedent for flashy E3 presentations with surprise cameos.

We also might learn about the fate of the Xbox 360. The aging current generation console may still have shelf-life yet for Microsoft, and the company teased it would tell fans what that might include at E3.

Sony

Sony announced its new PlayStation 4 in February, but has remained somewhat silent since. While its initial presentation was a long one, there are some big questions surrounding the PS4, including the actual look of the console.

Sony will have the task of countering Microsoft's recent press conference, and selling its console to gamers. The biggest questions will lie with its plans for online gaming, and if there will be to a subscription model similar to Xbox Live.

Sony's press conference is Monday at 6 p.m. PT/9 ET, and will also stream online. Mashable will be hosting a live blog of Sony's presentation starting a half-hour before.

Nintendo

Nintendo opted out of a traditional press conference for the first time in E3 history, instead opting to present its upcoming games via an online announcement Monday morning. This could be due to flagging Wii U sales, as the company struggles to regroup after a stuttering launch.

Nintendo is probably going to reveal some strong franchise favorites to entice fans to the Wii U, along with titles for the handheld 3DS, which has recovered well with a solid library after a similarly slow launch.

Other Big Publishers

Many publishers will trot out cross-generation and next generation titles at E3, and will have playable demos on the show floor.

Activision announced it will show the next iteration of its blockbuster military shooter Call of Duty: Ghosts, out Nov. 5, at E3. The game will be playable on both current and next-generation consoles, as well as PCs.

In addition, Activision will show off the newest addition to the toy-video game meld Skylanders Swapforce, which allows players to use toys that can be pulled in half and recombined for interesting new character combinations. It will also show off Bungie's upcoming, highly anticipated massive online first-person shooter, Destiny. There is still a lot for fans to learn about this game, which the ex-Halo developer has been working on in secret for years.

Electronic Arts will use E3 to show off many of its big-ticket sports franchises, include the newest entries to Madden and FIFA. It will also have a separate section of its booth just to showcase mobile games, including upcoming titles like Plants vs Zombies 2.

There might be some surprises up EA's sleeve at its big press conference at 2 p.m. PT/5 ET. We can expect some unannounced things, as well as previews of upcoming titles. That press conference can also be watched online, and we'll host a stream on Mashable as well.

Publisher Ubisoft is set to reveal more about its new intellectual property Watch Dogs, the open-world hacking game revealed at least year's E3 that stole the show. It's scheduled to be released on current and next-generation consoles.

Ubisoft will also show players more of Assassin's Creed IV: Black Flag where the player takes to the high seas during the early 1700s, where pirates ruled the waves. Additionally, South Park: The Stick of Truth, a game Ubisoft purchased during THQ's bankruptcy sale, will also be playable at E3.

Fans of superheroes will want to keep an eye on Warner Bros. Interactive during E3 — it will be showcasing Batman's newest title Arkham Origins, LEGO Marvel Super Heroes, and Scribblenauts Unmasked, which allows players to call upon every DC Comics character ever created to solve puzzles. There will also be one or two games that will be announced at the show.

Disney plans to pull back the curtain more on Disney Infinity, another game that uses plastic toys to control the action. It will also demonstrate an early build of Fantasia: Music Evolved, a game announced last week by the creators of Dance Central where players use the Kinect sensor to change the tempo, speed and effects on pieces of music.

Gaming Techonolgy

Of course, games won't be the only thing worth talking about at E3. Technology companies will be present to show off the newest gaming hardware and peripherals.

Nvidia will have the Shield gaming system on the show floor, which combines a controller and handheld screen to play Android games, as well as games streamed via the PC and Steam. It also plans to show off its newest GTX PC graphics cards.

Razer announced the thinnest gaming laptop it has ever created just two weeks ago, and the Blade will also be available for hands-on play on the E3 show floor. The Blade is just .66 inches thick and weighs only four pounds, while still packing high-performance graphics.

The $99, hackable OUYA will have a presence across the street from E3, in a building open to the public. The console has been shipping to Kickstarter backers, and should arrive on retail store shelves on June 25.

The virtual reality headset Oculus Rift will be holding demos at E3 as well. In addition, several independent games that harness the Oculus Rift will be playable at the IndieCade booth at E3.

This rundown only represents a smattering of what we'll see at this year's E3 — there will be plenty of other publishers, tech companies and independent game creators at the show. We'll keep the site updated with new information as it develops in Los Angeles this week, so stay tuned.
